There is a growing interest in the study of actinide chalcogenides due to the need for a better understanding of covalency and f�orbital participation in actinide�ligand bonding.  One goal of our research program is the development of new methods for the installation of these functional groups.  For example, we recently reported the synthesis of a U(IV) terminal sulfide, [K(18-crown-6)][U(S)(NR2)3] (R = SiMe3), via addition of KSCPh3 to [U(NR2)3], in the presence of 18-crown-6.  Formation of the terminal sulfido functional group in this example occurs via spontaneous elimination of the triphenylmethyl radical (Ph3C�).  In addition, we are exploring the utility of polychalcogenide, [En]2- (E = S, Se, Te; n = 2, 4), as novel chalcogen atom transfer reagents, and our efforts in this regard will be described.
